Cows are beasts of burden and a source of food in The City.
Cows[]
Guards can grumble about not having any cow meat in the cooks' stew, and that The Baron gets to eat cow.[1]
In the Stonemarket area, in Thief: Deadly Shadows, the background music has the barking of a dog, along with calls from turkey, roosters, and calves.
Bull[]
City Watch Officers are known as 'bulls' or 'bulldogs'.[2] A location visited in Thief: Deadly Shadows Mobile is the The Black Bull Inn.[3] The center of a target is a bull's-eye.[4][5]
Misc[]
While not cattle, mature and young Burricks are called bulls and calves, respectively.
Behind the scenes[]
While obviously not an animal, a .cow in DromEd is a file that saves missions and gamesys all in one, and only DromEd can read it.[6]
In the TDP quote scroll, Mahk states that he 'just saved cows'.[7]
